Load the default eeprom data when the content of flash/efuse is invalid.
This could help to eliminate some issues due to incorrect or
insufficient rf values.

If efuse mode is used, read all values from fw during eeprom init,
which makes it more convinient to check if rf values in efuse are
properly burned.

Clean up the flow of per-rate txpower limit setting to get rid of
duplicate work since it has already been handled by firmware, and set
proper max_power based on different channels and regdomains.

When the EEPROM data is read from flash, it can contain pre-calibration
data, which can save calibration time.
Note that group_cal can save 30% bootup calibration time, and dpd_cal can
save 75% channel switching time.

Add support for getting rf values from flash.
This is used for some test purposes and products.
If the mtd partition is configured in dts, driver will read from flash
to init eeprom command; if not, still init it with efuse's values.
An example:
&slot0 {
mt7915@0,0 {
reg = <0x0000 0 0 0 0>;
device_type = "pci";
mediatek,mtd-eeprom = <&factory 0x0000>;
};
};

Add support for the MediaTek latest generation IEEE 802.11ax 4x4
device MT7915E, which supports concurrent dual-band operation at
both 5GHz and 2.4GHz.
Note that this patch just add basic part and will add more HE
capabilities support in the further patches.
The driver supports AP, Station, Mesh and monitor mode.
